Add a self-healing backstop so recovery no longer depends on an event firing:
- periodic reconcile (every 8s): read-only drift check that runs apply ONLY when
broken (no headless / DP-1 not mirroring / workspace trapped on a mirror /
orphan / off-screen window) — no steady-state flicker.
- delayed reconcile 1.5s after a monitor event to catch late workspace
reassignment races.
- socat auto-reconnect; exit cleanly when the session socket vanishes.
New 'reconcile' subcommand. Verified: reconcile heals a deliberately broken
mirror and no-ops on a healthy state.
